GUI Options

see the GUIDE examples “Panel” on page 8-38 and “An Address B ook Reader

(GUIDE)” on page 10-81. Also see the example “Using Panel Containers in

Figures — Uipanels”, w hich does not use GUID E.

Command-Line Accessibility

You can restrict access to a GUI figure from the command line or from a code

file with the GUIDE Com mand -line accessibility options.

Unless you explicitly specify a figure handle, many commands, such as

plot,

alter the current figure (the figure specified by the root

CurrentFigure

property and returned b y the gcf command). The current figure is usually

the figure that is most recently created, drawn i nto, or mouse-clicked. You

can programmatically designate a figure

h (where h is its handle) as the

current figure in four ways:

1 set(0,'Curre ntFigure',h) —Makesfigureh current, but does not

change its visibility or stacking with respect to other figures

2 figure(h) —Makesfigureh current, visible, and displayed on top of other

figures

3 axes(h) — Makes existing axes h the current axes and displays the figure

containing it on top of other figures

4 plot(h,...), or any plotting function that takes an axes as its first

argument, also makes existing axes

h the current axes and displays the

figure containing it on top of other figures

The

gcf function returns the handle of the current figure.

h = gcf

For a GUI created in GUIDE, set the Command-line accessibility option

to prevent users from inadvertently changing the appearance or content

of a GUI by executing commands at the command line or from a script or

function, such as

plot. The following table briefly describes the four options

for Comm and-line accessibility.
